Application filed lu ly 3, 1912'. Scria'1-No.'707,505;

To'all whom it may] concern Be it known that I, JoI-IN ream, citi'-' zen of the United States, residing at Searsport, in the county of Waldo, Stateof Maine, have invented certain new and useful I mprovementsin lvave M'oto-rs; and I do hereby declarethe following to be a full,- clear, and exact description of the invention, such as will enable others skilled in the are to which it appertains to make and use the same.

This invention relates to improvements in wave motors.

The principal object ofthe invention is to provide a novel connection between a driven shaft and a reciprocatory float for imparting a continuous rotary movement in the same direction to the shaft upon movement of the float.

Another object of the invention is to provide a wave motor including a driven shaft, a drum loosely mounted on the shaft, a reciprocatory float, a cable connection between the float and drum, and connecting means between the drum and shaft for imparting a continuous rotary movement in the same direction to the shaft upon movement of the float.

A further object of the invention is to provide a motor of the character described which is extremely simple in construction, it being composed of a minimum number of parts and is therefore cheap to manufacture.

Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended; it being understood that various changes in the form, pro-portion, size and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a detail view of a wharf showing the application of a wave motor constructed in accordance with my invention, Fig. 2 is a detail sectional View taken on the line 22 of Fig. 1, Fig. 3 is a detail sectional view taken on the line 83 of Fig. 1, Fig. 4 is a detail top plan view, Fig. 5 is a longitudinal sectional view through the. drum and driving. con

n'ection, and .Fig. 6' is a detail end view of the weight and supporting pulley.

Like reference numerals -designate cor-re sponding parts in all the figures of the drawings. I

Referring to the deawingai 5 designates a vvha'rf, and mounted upon this wharf are brackets 6" 6 which rotatably support a driven shaft 7 Loosely mounted upon this shaft :is a drum 8, the outer end thereof being counterbored, as at 9,-to receive-a ratchet whecl lO which is fixed to the shaft 7. A plurality of pawls; 11 are mounted upon the outer face of the drum 8 for engagement with the ratchet wheel 9, and these pawls are yieldably held in engagement with said wheel by means of springs 11?.

Trained around the drum 8 is a cable 12, one end 13 thereof being connected to a float 14; which is balanced by means of water 15 or other suitable weight. The other end 16 of the cable is connected to the bottom of the float 14, and this end of the cable is trained under a groove pulley 17, the axle 18 thereof being connected by a clevis 19. Centrally connected to this clevis is a chain 20 or other suitable means for supporting a weight 21. This weight tends to normally hold the cable 12 in taut relation. It will thus be observed that as the float is elevated by reason of the waves, the cable will cause the drum 8 to rotate in a direction whereby the pawls 11 will engage the ratchet 10, and thereby transmit rotary movement in one direction to the shaft 7. In order to further transmit rotary movement in the same direction to the shaft 7 during the descent of the float 14:, the following mechanism is employed: The inner face of thedrum 8 is formed with a bevel gear 22, and loosely mounted upon the shaft 7 in spaced relation to said gear is a bevel gear. 23, said bevel gears being held in spaced relation by means of a spacing sleeve 24:. These gears are operatively connected by means of a beveledpinion 25 which is to l rotatably mounted upon a stub shaft 26 carried by a bracket 27 which is secured to the wharf 5. The outer face of the bevel gear 23 is formed with a counterbore 28, and

disposed within said counterbore and fixed to the shaft is a ratchet wheel 29, the teeth gear 23, and are yieldably held in engage ment with the ratchet Wheel 29 by means of coil springs 31. It will thus be observed that when the float 14 descends, the cable 12 will cause the drum 8 to rotate in the opposite direction, and as a result, this drum will cause the pawls 11 to ride over the ratchet wheel 10 and not actuate the shaft 7. This rotation of the drum however will, through the medium of the bevel gear 22 and pinion 25, cause the bevel gear to rotate in a direction opposite to the rotation of the drum, and this bevel gear 23 will, through the medium of the pawls 30 and ratchet Wheel 29, transmit rotary movement to the driven shaft 7 in the same direction as when the float is being raised.

From the foregoing, it will be observed that as the float reciprocates, the drum will be oppositely rotated, and through the driving connection above described, the shaft 7 will be rotated continuously in the same direction. It will also be observed that this motor will be operated by the rise'and fall of the tides.

What is claimed is: In a wave motor, the combination of a shaft, a drum loose on the shaft, a float, a'

cable trained around the drum and connected at its ends to the float, a pulley supported by the cable below the float, a weight depending from the pulley, and an operative connection between the drum and shaft Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
